Summary (CIE 9700) Biology A2 - Photosynthesis

Photosynthesis Content: 1) Energy transfer a) ATP and NADPH from light-dependent reactions to light-independent reactions b) ATP and NADPH are used during the Calving Cycle to produce organic molecules c) sites of light-dependent and light-independent reactions in the chloroplast d) role of chloroplast pigments (chlorophyll a, chlorophyll b, carotene and xanthophyll) e) accessory (carotene and xanthophyll) vs primary pigments chlorophyll a and chlorophyll b) f) absorption and action spectra g) stages of light-dependent and independent reactions 2) Limiting factors a) limiting factors and rate of photosynthesis b) light intensity, CO2 concentration, and temperature on the rate of photosynthesis 3) Adaptations a) C3 and C4 plants b) structure and functions of chloroplast c) physiology of C4 plants d) C4 pathway to avoid photorespiration
